The USB Flash Drive provides you with a paperless system for certificates to be easily accessed and maintained over time. USB Flash Drive can be returned each time the Cal-Paks® are recalibrated and the new NVLAP Certificate will be added to the Flash Drive. This provides a detailed history of the weights all in one convenient place with no paperwork to keep on file.

Supplied in a rugged polycarbonate case with each individual weight in its own high quality polycarbonate case. Accessories for proper handling and care of weights are also included.

Components and carrying case are linked through the use of a unique serial number. You can trace your individual weights to the appropriate NVLAP Certificate and master carrying case.

PLEASE NOTE THE LEAD TIME! Calibration weights with certificates are not an off-the-shelf item, no matter who you purchase them from. The manufacturer performs the calibration on each Cal-Pak as the order comes in. The lead time is 2 - 3 weeks.
IF YOU CAN'T WORK WITH THIS LEAD TIME - DON'T ORDER THIS WEIGHT SET!

All
calibration weights are not returnable. Once
your order has been placed it CAN NOT be cancelled.
Please carefully consider this prior to placing your order.
The reason for this is these weights are custom manufactured
and are certified on the date they were made. In addition,
if you touch the calibration weight with your fingers
the oil in your skin would change the tolerance and we can
not take this chance if the weight was returned.

Construction and General Shape:

Troemner Calibration Weights 1 gram and larger consist of a body and a lifting knob. The lifting knob is specifically designed for use with forceps, tweezers or some other lifting device. Weight bottoms are slightly recessed to expose the smallest possible area to wear. Each weight is marked with its nominal value.

Weights 500 mg and lower are made of sheet metal and are one-piece construction with one side turned up to make them easy to handle with forceps. Depending on the class, these weights may or may not be marked with their nominal value.

Surface Finish:

All surfaces are polished to a perfect, mirror-like finish and conform to specifications in ANSI/ASTM E617

Polycarbonate Cases for Individual Weights:

To safeguard your Troemner Alloy 8 Stainless Steel Precision Calibration Weights, attractive, durable, high quality, polycarbonate cases are provided with weights 1 mg through 2 kg. The polycarbonate cases feature a custom insert, bumper, and locking lid to assure weights are held securely within the case and avoid movement. Polycarbonate cases for weights greater than 2kg are available at an additional cost.

It is recommended that the weight selected to calibrate a balance and/or scale have a tolerance small enough as not to be detected by the balance and/or scale. Troemner recommends the tolerance of a weight selected for calibrating a balance and/or scale is no more than 1/3 of the readability or precision of the balance and/or scale being calibrated. If this cannot be achieved, it is suggested that a Class 1 Electronic Balance Calibration Weight with a NVLAP certificate be ordered which provides the actual mass value for the weight which reduces measurement uncertainty.

Electronic Balance Calibration Weights can also be used to check or verify the accuracy of your balance and/or scale between calibrations. It is recommended that the user check a balance and/or scale prior to each use. Keeping the weight at or near the balance and/or scale keeps the weight at the same temperature as the equipment.

The
weight value can deviate above or below the nominal value
by the tolerance defined. To determine the tolerance
of a mass, look at the denomination or nominal value of the
weight and the appropriate class you need.

Certificate Options

Traceable Certificate

The Traceable Certificate is designed for those laboratories and companies that require traceability, but do not need to meet any stringent regulatory requirements. The Traceable Certificate measurement process is based on a single standard and utilizes one series of comparisons The Traceable Certificate includes nominal value, mass correction, uncertainty and tolerance for each weight in addition to the basic customer information such as name, address, purchase order number, date of calibration, accuracy class, density and statement of traceability to NIST.

The NVLAP Accredited Certificate provides compliance in both measurement process and data reported to the customer to meet a variety of standards including NVLAP Handbook 150-2, ISO/IEC 9000, ISO/IEC 17025, FDA, GMP, GLP, DOD, ANSI/NCSL Z540-1, and nuclear requirements. The NIST administered National Voluntary Laboratory Accreditation Program (NVLAP) approves, through periodic audits, all processing and weighing procedures, as well as certificate format and content. Calibration procedures vary by tolerance class requested. For example, for higher accuracy classes such as Troemner Class 0 and 1. Troemner performs a multiple weighing procedure utilizing their secondary working standards to determine the mass of a customer's weight. Procedures and processes used to generate this multi-page certificate, as well as its format and content, are prescribed by NVLAP. Users held absolutely accountable for their weights should order weights with NVLAP certification.
